### 3/5 — Good start but missing features

*2023-07-23*

I like to do measurements with a test CD on my turntable using my iPad.

Pros:
IPad is supported with Oscilloscope and Spectrum available. Also my attached RME ADI-2/4 audio interface that I use as Phono Preamp and ADC nicely works. Great that it supports the sample rate of 96kHz.

Cons:
Display of only one single channel of the stereo input and no simultaneous display of the right and left channel. This is true for Oscilloscope and Spectrum. So comparisons between both channels cannot be done easily.
Also missing a X/Y display that is vital for antiskating adjustment.
In Oscilloscope view of a sinus input signal the display is not triggered so no still standing Sinus can be seen.

Summary:
If the missing functionality would be available the price would be Ok for me. But with all the cons it was wasted money for me as I could not achieve what I had expected.

### 3/5 — Only 60seconds of a file

*2023-06-23*

I can only put 60 seconds in so if I have a 6 minute long mp3 file I can only view 60 seconds of it

### 3/5 — doesn't work with airpods pro

*2022-12-05*

very good possibilities to analyze, but no connection to the airpods pro with ipad pro M1 2021

### 4/5 — Good but crashing

*2022-07-11*

I love it but it crashes when I use the Octave RTA

### 3/5 — Pretty would like some changes

*2021-11-17*

All most able to be my RTA in a live environment 

First for live use i would really like the Octave RTA to be even slower so if there’s a big bit of feed back that’s fast I can catch it.

I would like to move the PIP on the screen or do like a half and half have the spectrograph rotated 90 degrees and under the octave RTA, 

Also when selecting a band on the RTA I would like to set a option where it will disappear when I lift my finger off the screen 

If these features are added I would recommend this app to anyone other then that it’s pretty good for how much it costs and would like too a update with some added features :)

### 3/5 — Limited use

*2016-06-17*

It's good for short loops and audio files but from what I can see that's about all. When you can only analyzer music that is less than 220 seconds long, not very practical. What am I supposed to do, chop up the song? Maybe I'm missing something here?

### 4/5 — pitch labels please!

*2016-05-25*

This is a very useful app and one of the few of its kind that has been updated recently.
What would make it perfect would be for it to display the musical note name alongside the frequency display. For me that would make it a 5* app.

### 4/5 — Music analysis

*2016-04-14*

It's a useful app, but would be so much better if it could analyze the tunes in your music library (i.e open & playback a song)

### 4/5 — Wow. Nifty audio visualization

*2015-11-01, version 2.3*

RTA is cool, though a little surprising you need to start recording to see it. 

Flexible display and settings. Even trigger start. 

Would like overlay for musical scale notes, ideally with optional transpose for things like B-flat trumpet. 

And use of headphone microphone.

### 4/5 — my favorite spectrum analyzer

*2015-05-11*

I practice playing a Bb trumpet using this spectrum analyzer, chromatic tuner, metronome, and audio recorder. Studying my sound in the frequency and time domains helps improve my playing. 

I would suggest the following feature to be added: Allow the user to preset the range of frequency and time. The current version allows the user to zoom in or out using 2-finger gestures. Because the region of interest for me is between 0 and 3 kHz, and because I need to view that region in detail, I need to adjust the frequency scale every time I use or reset the app. Furthermore, the 2-finger gesture sometimes bounces the scale such that the origin is not 0 kHz 0 seconds. Allowing the user to select the default range of frequency and time would save lots of time. 

Thanks for a nice product.

### 3/5 — shameful oversight?

*2015-04-06*

The program is well done, looks good, and is ALMOST useful. The external mic input accessible via the earphone jack was not included. I'll give it 3 stars for what the software can do, but I'm taking 2 stars away for the their obvious stupidity. Had they included it I could analyze signals on wires, not just from the microphone. Yeah the camera adapter and USB mic might get me that ability too but why should I have to spend another $30-$50 because they screwed up? It's great software, I've no complaints about that, but functionally, it's just had a perfectly healthy leg amputated. 
Fix this with an upgrade and it's a five star program.

### 5/5 — Neat App

*2014-12-29*

Very nicely done by the creators of the app.  Several nice choices with the window functions, different options on displays, spectra, sonograms, and oscilloscope.  Good value.

### 5/5 — Best audio bang for the buck

*2014-12-20*

I have been an audio engineer for over 25 years. I've owned a jingle production company, a 2" 24 track recording studio and have been a live FOH/Monitor engineer for the better part of those 25 years. Obviously with the advancement of technology it gets better and cheaper every day. But this app has brought the power and ease-of-use and flexibility that only a year ago cost close to $1000. Can't believe it's under $10.

### 1/5 — Audio Recording Playback Broken

*2020-09-25*

Captured Audio recordings do not play-back on iPadOS 13 or iPadOS 14 devices.

The analysis window shows the captured Spectrogram, Spectrum and associated data - but recorded audio will not play back.

### 1/5 — Audio Analyzer

*2019-06-04*

I just purchased for $20. App does not work on my iPhone X with latest iOS. App does not pass a request to use the knternal microphone to Settings. The list of apps requesting to use the microphone remains empty. 
An instuction to turn mic on in Setings appears but the app itself never adds itself to devices requesting the microphone.

When tapping the Gear symbol, the screen blinkx for 1/2 sec to an audio setup page but the returns to home screen. I tried several downloads and phone reboots. 

No idea what to try next. There is no instruction manual or support email. Need to request a refund.

### 1/5 — Total Waste of Money

*2019-05-30*

As an Analyzer software, you have one crucial job to do. Show an accurate representation of the frequency spectrum. This app doesn’t even come close. I put this app on my tech bench and ran a high end Goldline tone generator into it, which the goldline and my audio interface was double checked with an oscilloscope for accuracy. This app shows major peaks and dips from 28Hz all the way up to 1.5kHz. It looks like a freaking roller coaster! It only gets mildly accurate after 1.8kHz. This basically makes the app unusable. I would have attached a screenshot if that option existed. SO aggravated. I have another Analyzer app that’s almost spot on to what the tone generator is putting out, but doesn’t have some of the options this app does (hence purchasing this one). Please fix the accuracy of this app or give me my money back

### 1/5 — oh!no!!!

*2015-07-05*

iOS8.4 update not available…

### 1/5 — Bought and thought it realtime

*2014-12-25, version 2.2*

Great engine, but can't get it working for realtime analysis, saw a long list of features but.... no RTA, that is why I'm disappointed.

### 1/5 — Doesn't do what it's supposed to

*2014-10-05*

Purchased this app because it's the only one I can find that advertises the ability to open files from other sources (saved via apple's voice memos app on an iPhone 6) but when I attempt to open the file, the app just crashes.

### 1/5 — No audiobus

*2014-09-27*

Without audiobus its mit worth the Money

### 2/5 — Needs Inter-App Audio support

*2016-05-31*

This is a good app, but not all that useful if it can only analyse the device input. If it had IAA support I'd give it 5 stars.

### 2/5 — Importing issues

*2016-05-09*

App crashes when trying to import files from voice memos on phone..please fix

### 2/5 — It is what it is

*2014-08-07*

This app looks really good if you reverse the colors on your phone. It's seems like a lot of money for an app that doesn't seem to do any more than the cheaper ones that do the same thing. I mean unless I can edit the junk noise out of my recordings manually I don't see the point for the extra money.

### 5/5 — Best iOS analyzer!

*2026-04-16*

Been using this analyzer on iPads and Phn professionally for years. Its dual ease of use and extreme accuracy makes it a no brainer.
For those not wanting or use Smarrt, it’s a win!

### 5/5 — Amazing app (only jealous people would dislike it and give it poor ratings).

*2026-04-15*

This is especially a great study tool for opera singers. 
It not only reveals technique imbalance in our own voices, but can help seek out credible role models to listen. 

Bonus: Holding our phone (with this app running) up against a speaker — through which a singer’s voice is heard — can help us analyze the quality of that singers voice technique.

(Live singing can also be analyzed, but one will need to be close to the source.)

I’m grateful for the creator for this app! 
I try my best to promote it via word of mouth… to colleagues, etc.

### 5/5 — Accurate, Smooth and Sophisticated

*2024-06-03*

Everything I was looking for in a Spectrograph app. Export, frequency checking, zooming and scrolling in time and frequency domains, plus all processing options. Love it.

### 5/5 — Great for singers

*2023-01-11*

This is a great app for singers who would like to improve their resonance. It allowed me to experiment with different vowel sounds from shaping my vocal tract in different ways to improve resonance.

### 5/5 — Solid app

*2022-06-05*

Tried a few spectrogram apps and this one is pretty solid. Lots of customization features.
Only small thing I would wish is that we can start replaying an audio file with the spectrogram completely scrolled back so that no one can anticipate what’s coming. But otherwise great job.

### 5/5 — My "Go To" App for Live Sound

*2017-07-03*

When I want to know what I am missing in a mix or to find a problem frequency, Audio Analyzer tells me and takes the guess work out of making needed adjustments to the mix at our church. ID ringing frequencies with the RTA or spectrograph or double-check your EQ at a glance. Intuitive to use and definitely worth the $4.99! Thank you for making such a great app!!!

### 5/5 — So far, awesome

*2017-04-23*

Exactly what I need to ring out FOH and monitor wedges. Waiting for micW i436 to arrive. 5 stars will stick if the app performs with the external mmm microphone.

### 5/5 — love it!

*2016-02-22, version 2.3*

I love this app, a very useful tool in many contexts.

### 5/5 — Excellent app!

*2016-01-08*

Very thorough and well thought out.

### 5/5 — Works Well with Phonetic / Parfait pour la phonétique

*2015-08-01*

(English Follows) Très bonne application pour la phonétique. Je suis débutant pour la langue thaïe, cette langue à 5 tonalités. Pour un Occidental, cela est très difficile de savoir si notre prononciation est juste, car nos langues n’ont pas cette spécificité (ou si peu). Avec cette application, je peux enfin m’exercer seul et voir immédiatement si je suis sur la bonne tonalité. Je ne suis pas un ingénieur de son et je ne savais pas trop comment produire le spectrogramme parfait pour mes cours. J’ai demandé au concepteur de l’application s’il pouvait me donner le réglage pour ce type d’exercice. Il a répondu avec empressement et tout est parfait. (Le réglage est à la fin pour ceux qui sont intéressés.)

Very good phonetic app. I’m a Thai language beginner learner, this language has 5 tones. For an Occidental as me, it’s very difficult  to know if the tone I produce is right, because our languages have not this specificity. With this app, I can now practice alone and immediately see if I produce the good tonality. I’m not a sound engineer and I didn’t know how to adjust the setting. I asked to the app programmer if he can gave me the setting for this exercise type. He responded quickly and all it’s now perfect. (The setting follows if you’re interested).

There are I think the best settings in your case:

Window size: 4096
Window type: Hanning
Sample rate: 44.1kHz
FFT calculations interval 1.5ms
Frequency display size: 2048
Amplitude scale: decibels
Frequency scale: logarithmic -> when you want imitate voice flow
Frequency scale: linear -> when you want imitate vowels formants in your sound

When you are using linear frequency scale you have to zoom your spectrogram to region 0-5kHz (using pinch gesture)
